Quadcopter arm Replacement

Quadcopter/Hexacopter arm replacement with round shape to reduce resistance for propeller. Designed for 2212 920KV and GF2215/20 motors. Also oval shape helps reduce bending and flipping of arm comparing with flat versions.

quad_leg_2212 920KV_hole_for_wires_oval version is with added center oval hole 6x4x4 mm size.

quad_leg_2212 920KV_9_20150111 - version with removed leg and increased resistance of bending in perpendicular direction according motor axis.(Problem is that: When motors with propeller are not balanced correctly there is bending vibrations in perpendicular axis vs. motor axis).
